Question

我转换了一个完美的Managed C ++ DLL项目，该项目使用从VS2008到VS2010的非托管C ++ LIB。事先我用VS2010分别重建了LIB（它们是我无权管理的另一个项目的一部分）。但是，转换后我的托管DLL项目停止链接，给我几个LNK2001错误消息（请参阅下面的示例）。关于在“string”和“iosfwd”标题中定义的“std”实体的所有错误。我缺少哪些编译器/链接器设置？

提前感谢您的帮助。

终于找到了它（感谢Hans Passant的提示！）我有一些文件仍由VS2008构建，导致了这个问题。感谢所有打扰添加评论的人。

从VS2008转换到VS2010后，C ++ / CLI DLL项目停止链接
